This is hard but some of my picks would be:Kevin Spacey in American BeautyMalcolm McDowell in Clockwork OrangeTom Hanks in Forrest GumpBale in American PsychoJake Gyllenhaal in NightcrawlerAnthony Hopkins in SOTLAnd then the list is incomplete without Godfather. Or you could add Brando for On the Waterfront and Al Pacino for Scent of a Woman.

It’s not up to me which performance gets on the list. They are chosen as favorite’s by the members of this forum. So it would be nice if I can add one for you. Would you Ike to pick one? Brando in Godfather...?

I don't think Keljin and Kakunamatata were ever active participants of the poll board. The problem with these types of polls, especially on the old poll board, was that anyone with any motivation could post a suggestion. When I first did this type of poll, I copied from cocoken, who was a prolific poll author but is no longer on IMDb, and set up guidelines about who could "nominate" a favorite: something like someone who has posted on the poll board at least twenty times prior to when the poll was first suggested and leaves thoughtful and considerate feedback. I stopped doing that, to try to be more "democratic," but I think it's a fair guideline and I might add that to my "performances by child actors" poll, although trollers and so-called "fanboys" are less likely to come onto GS, fortunately.

You are right. I also think they were never active on the poll board. I removed those two:Leonardo DiCaprio as Calvin Candie in Django Unchained (2012) - Kelljin's favoriteLeonardo DiCaprio as Billy in The Departed (2006) - Kakunamatata's favorite

Yes, I saw the picture. I was looking for a better picture. I think it's better if William is alone on the picture, but I couldn't find a good one.Only this one:http://www.imdb.com/title/tt0025878/mediaviewer/rm726600704But this one seems not a shot of the movie.I changed the picture into the one you suggested.

Thanks for using my recommended image. The one in your last post isn't William Powell though, it is another actor from the first 'Thin Man' film.

William Powell made over 90 movies in his long career, the first in 1922 & the last in 1955 (Mister Roberts). I love all of his films but my favorites were from the 30's & 40's. If you can't find the 'Thin Man' movies try any of these:

Good poll, unfortunately I arrived very late, one of my favorite interpretations is already on the list; Dicaprio as Jordan Belfort and Sean Penn as Jimmy Markum. However I would like to choose Leonardo DiCaprio as Howard Hughes in 'The Aviator'
